<h3 id="rationale">Rationale:</h3>
<p>In Bash and Ksh, you can use <code>. myscript arg1 arg2..</code> to
set <code>$1</code> and <code>$2</code> in the sourced script.</p>
<p>This is not the case in Dash, where any additional arguments are
ignored, or in POSIX sh where the behavior is unspecified.</p>
<p>Instead, assign arguments to variables and rewrite the sourced script
to read from them.</p>
